B and D can also constitute a pleasant sound as they are also similar to A.

Also, B and D can be more musical than A because they change frequently, constituting a pleasant sound, whereas A is a single monotone.

This question isn't related to any pleasant or unpleasant sound. Also, if the distance travelled by the sonic vibrations is 2x, time is 2 seconds and speed is 1.5 km/s, the distance= speed*time=1.5*2=3 km. The answer should be 3 km, not 1.5 km. SOF is requested to kindly rectify this error.
